(54) MULTI-FUNCTIONAL PIXELS DESIGNED FOR TRANSMISSION MATCHING IN TRANSPARENT DISPLAYS


(57) One embodiment illustrated herein includes an optical device. The optical device includes a stacked device, formed in a single semiconductor chip ,configured to be coupled in an overlapping fashion to an underlying device. The stacked device includes a plurality of optical output pixels. Each of the output pixels includes a plurality of subpixels. Each subpixel is configured to output a color of light. Each pixel is configured to output a plurality of colors of light. The optical device further includes one or more detectors, configured to detect light, interleaved with the subpixels of the pixels. The stacked device comprises a plurality of transparent regions formed in the stacked device between the pixels. The plurality of transparent regions are transparent, according to a first transmission efficiency, to light in a first spectrum. The underlying device emits light in the first spectrum.
